American visa F 1 requires supplementary materials in the mailbox, but what should I do if I send supplementary materials and don't receive any reply? Is this a check?

If you have submitted supplementary materials by email according to the requirements of U.S. visa F 1, but have not received any reply, it may be due to the following circumstances:

1. The e-mail address is wrong or the message is blocked by the spam box. You can confirm whether the e-mail address you provided is correct, or check whether there is any relevant reply in the spam box.

The visa office is reviewing your materials. When applying for an American F/KLOC-0 visa, if your materials are incomplete or need further examination, the visa office may ask you to provide supplementary materials. Once you provide supplementary materials, the visa office needs time to review and process your application.

The visa office may contact you in other ways. If you provide multiple contact information when applying, the visa office may contact you through other means (such as telephone or email).

If you are not sure about the status of your application, you can check the relevant information through the official website of the visa office or telephone consultation channels.
